Ground penetrating radar detection of hidden defects in the seawall

摘要

For the existence of the potential safety risk, it is necessary to reveal the distribution of these hidden defects in the seawall body. Based on the analysis of seawall engineering and foundation characteristics, ground penetrating radar (GPR) has been used to identify the hidden defects and quality status of loosening weak layers in the seawall body (clay). The detection results are in good agreement with the drilling results, and it can be used as an important basis for the seawall safety evaluation.
